3RT2046-1KB40 SIEMENS

The 3RT2046-1KB40 power contactor from Siemens is a high-performance switching device designed for AC-3 applications, specifically controlling motors up to 45 kW at 400 V. With a rated current of 95 A, this 3-pole contactor (3 normally open contacts) is well-suited for demanding industrial environments. It features an integrated varistor for surge suppression, protecting sensitive electronic components from voltage spikes. The contactor includes one normally open (NO) and one normally closed (NC) auxiliary contact, providing additional flexibility for control and monitoring circuits. Its 24 V DC coil allows for direct control from programmable logic controllers (PLCs), and it's specifically designed to be compatible with 2 A PLC outputs. The size S3 designation indicates its compact dimensions, optimizing space utilization within electrical panels. Screw terminals ensure a secure and reliable electrical connection. This contactor is ideal for applications requiring frequent switching and high operational reliability. Siemens' 3RT2 series is known for its robust design and long service life.
